13 Claims. 1

This invention relates to motion-translating devices for converting arelatively continuous motion into motion which has high-speed pulses atpredetermined intervals and it has particular relation to jump-typeregister or counting devices suitable for integrating meters.

In accordance with the invention, a motion translating device includestwo rotatable members such as gears coupled to a common input membersuch as a pinion. The drive ratios differ for the rotatable members toproduce a differential motion of the members. The construction of oneofthe members which may involve removal of certain teeth in one of thegears) permits'biasing'means to move the member rapidly for apredetermined distance during each revolution of the member. Such atranslating deviceis particularly suitable for driving counting devicesor registers.

It is, therefore, a first object of the invention to provide an improvedmotion translating device for converting an input into an output motionhaving high speed pulses at predetermined intervals.

It is. a second object of the invention to provide an improved jump-typecounting device.

It is a third object of'the invention to provide a motion-translatingdevice having two rotatablemembers driven at different rates, one memberbeing constructed to, permit biasing means to restore the memberstopredetermined relative positions at predetermined intervals.

It is a fourth object of. the invention to provide a counter deviceoperated by the output of a translating device as set forth in the preceding paragraph.

Other objects of' the invention will be. apparent fromthe.followingdescription, taken in conjunction with the accompanyingdrawing, in which:

Figurel is a view in perspective of a' counting device embodying theinvention;

Fig. 2 is a view in side elevationiwithparts' broken away, showingaportion of the device illustrated in Fig. 1; and

Figs. 3 and tare detail views in side elevation showing the positions.of certain parts of the counting device of Fig. 1 under difierentconditions.

As previously pointed out, a motion-translat ing'device embodyingtheinvention may be employed for driving various mechanisms. Since it i isparticularly suitablev for driving counter. de

vices or registers, it will be described in connec-: tionwithaconventional counter device. Referring to the drawing, Fig. 1 showsa counter device A which may be of conventional construction. In thespecific embodiment illustrated, the counter device is of the cyclometertype and includes four counter wheels I, 3, 5 and l which are mountedfor independent rotation on a shaft ll. These counter devices have adrum configuration and each may have a hub [3 for receiving the shaftII.

For transmitting motion. from one counter wheel to a succeeding counterwheel a plurality of pinions 21, '29 and 3| are mounted for independentrotation about a shaft 33. These pinions are associated with the counterwheels in "is same manner in which pinions bearing the same referencecharacters are associated with. counter wheels bearing the samereference characters in the Barnes Patent 2,365,510, which issuedDecember 19, 1944. The operation of the counter wheels and the pinionswill be under stood from a study of the aforesaid Barnes patent.

It will be understood that the counter wheel '1 may be arranged forrotation in either direction about the shaft II. In the presentembodiment, it will be assumed that during a normal counter operation,the counter wheel 1 rotates in the direction of the arrow 2|. It will benoted that this direction is opposite to the direction of rotationassumed in the aforesaid Barnes patent.

Each of the counter wheels includes a cylindrical rim [5 which carriessuitable indicia [9. In the present embodiment, the indicia on thecounter wheels take the form of ten numerals 0 to 9, inclusive, whichare equally spaced about the cylindrical surface of the counter wheel.

It will be understood that for each full revolution of the counter wheel"I, the counter wheel 5 is actuated in the same direction for an angulardistance equal to the spacing between successive numbers thereon for thepurpose of transferring the reading of the wheel I to the wheel 5.Similarly, the counter wheel 3 is actuated by the distance betweensuccessive numbers thereon for each revolution of the counter wheel 5and the counter wheel i is actuated by the distance between successivenumbers for each revolution of the counter wheel 3. The counter wheelsI, 3, 5 and I may be designated for example, thousands, hundreds, tensand units counter wheels. During the rotation of the counter wheels,each counter Wheel presents the numerals thereon successively at aviewing point in the form of a window 23 in a face plate 3 which isillustrated in broken lines. In Fig. 1, the counter wheels arepositioned to indicate the quantity 9990 through the window 255.

Each movement of one of the counter wheels 2, 3 or 5 takes place onlywhile the preceding counter wheel moves from a position exposing thenumeral 9 to a position exposing the numeral 6 thereon. In order toprevent erroneous read-- ings of the counter device or register, it isdesirable that such motion take place rapidly or with a jump action.Such jump operation is provided in the embodiment of Fig. l.

The counter device A may be employed for counting the revolutions of ashaft 35 which may, example, be the output shaft of a conventional\vatthcur meter. This shaft is coupled to the counter device through amotion-translating device B.

The motion-translating device B includes a pair of rotatable memberssuch as gears 3'5 and 39 which are rotated at different rates inaccordance with rotation of the shaft 35. To this end, the rotatablemembers 3'. and 39 may be coupled to the shaft through a pinion 41 whichengages both of the rotatable members 37 and 39 and a worm wheel 23which meshes with a worm l5 secured to the shaft 35.

The rotatable member 39 is so constructed that it is uncoupled from theshaft 25 at predetermined intervals. When the rotatable member 3% isuncoupled from the shaft 35, biasing means (described below) returns therotatable member to a predetermined position relative to the rotatablemember Such return is employed for advancing the counter wheel 3 rapidlyfrom a position exposing one numeral through the window to a positionexposing a succeeding numeral through the window.

the rotatable member 3?; is in the form of a gear, it may be uncoupledfrom the shaft by omitting certain teeth of the gear to provide amutilated gear having a. peripheral recess or gap 3?. This gap 1"! inthe mutilated gear is proportioned to permit movement of the gear 39 fora distance sufficient to move the counter wheel '5 through the angulardistance between successive indicia on the counter wheel. Although twoor more gaps similar to the gap i? may be provided at spaced intervalsabout the periphery of the gear in order to provide several jumpoperations du' ng each revolution of the gear, only one gap is requiredfor the counter device A.

As shown in Fig. 2, the rotatable member or gear is secured to the shaftii for rotation therewith. The rotatable member or gear 3'! is mountedon the shaft l l for rotation relative thereto. A spacer it may beinterposed between the hub of the counter wheel I and the gear 3'1. Anadditional spacer 5i may be interposed b..- tween the two gears 31 and39.

Suitable biasing means such as gravity or spring means are provided forbiasing the two gears 3'? and 39 towards a predetermined positionrelative to each other. Although the biasing means may be constructed topermit relative motion of the gears in only one direction, preferably itis constructed to permit substantial relative mo tion of the two gears3'! and in either direction.

In the preferred embodiment herein illustrated, spring biasing means areemployed. The gear is provided with a protuberance 53 in the form of apin which projects towards the gear 3%. In addition, the gear 38 isprovided with a protuberance or pin 55 which projects towards the gearThese pins are spaced by diiferent distances from the shaft H and areparallel thereto. Consequently, the pins may rotate past each otherwithout interference.

A. spring is coiled about the spacer 51 and '0 ends or arms 51a and arelocated on opposite sides of the pins 53 and 55. It will be noted that aplane transverse to the shaft ll intersects both of the pins 53 and Bylocating the ends or arms of the springs adjacent this plane, such endscan engage both of the pins.

As shown in Fig. 3, the ends 51a and 51b of the spring are biasedtowards each other to the pins and 53 towards positions wherein the pinsand the shaft H are substantially in a common ane. The gear 38 may bemoved in l either direction relative to the gear 37 against theresistance of the spring 5'5.

As pointed out in the discussion of Fig. l, the gears 31 and are d ironat different rates by the rotation of the shaft Conveniently, such ratesin 5 provided by employing different pitches for the teeth on therespective gears. The differential motion of the gears should besufficient dur ng each revolution thereof to move the gears relative toeach other by the angular distance represented by the spacing betweensuccessive numerals of the counter wheels.

In the specific embodiment herein disclosed, the gap i": represents anare having an angular equal to substantially one-tenth of 360 36. Thisis the angular distance required to move the coun wheel I an angulardistance equal to the spac .ig between successive numerals t ereon. Toillustrate further suitable values, the gears and may have the samediameter.

The ge may be a conventional gear having thirty teeth. The gear 39 alsohas thirty-six teetl but these are indexed in the 324 of peripheraisurface left on the gear 39 by the gap 4'1.

The relationships of the teeth in the two gears are shown in Figs. 3 and4. In order to distinguish between the teeth on the two gears, the teethT on the gear 13'; are illustrated as being cut som what deeper than theteeth t of the gear However, the teeth need not be different in depth inactual practice.

The gap 41 in the gear 39 is located between two of the teeth ti and t3.The number of teeth selected for the gears preferably is such that whenone tooth or the gear 3'! is directly behind the tooth ii in Fig. 3,another tooth of the gear 31 is directly behind the tooth t3. This isnot essential if it is unnecessary to permit movement of the gears ineither direction. However, if movement of the gears in either directionis desired, the aforesaid selection of the numbers of teeth facilitatesproper engagement of the pinion 4| with the teeth during rotation of thepinion in either direction. Teeth ti and t3 need not be exactly alignedwith two teeth of the gear 3'! but the displacement from such alignmentshould not be so great that the teeth interfere with or jam the pinionM.

In the embodiment herein illustrated, it will be noted that a commonpinion 4i engages both of the gears. If desired, the pinion 4| may beconstructed in two sections each engaging a sep arate one of the gears.Each section of the pinion then may have a tooth formation selected forthe associated gear. However, in actual practice, it has been foundsatisfactory to employ a single uniform pinion for both of the gears. Itwill be noted that the pinion illustrated in the drawing has six teeth.

It is believed that the operation of the inven- 5 tion now may be setforth. In Fig. 1, it will be assumed that the gearing between thewatthour meter shaft and the gears 3'? and 39 selected to producerotation of the gears in the direction of the arrow 6|. It will be notedthat the gap 4! has just passed the pinion 4|. The numeral of thecounter wheel 1 is exposed through the window 23. As the gap leaves thepinion 4|, the gears and pinion have the relationship illustrated inFig. 3. It will be noted that the pins 53 and 55 in the shaft II aresubstantially in a common plane. As the pinion 4| continues to rotate itgradually moves the gear 39 and the connected counter wheel 1 relativeto the gear 31. Such diiferential motion is produced because of theprovision of difierent pitches for the teeth on the two gears.

When the pinion 4| next engages the tooth tl, the parts are in theposition illustrated in Fig. 4. It will be noted that the pins 53 and 55now are spaced by an angular distance corresponding substantially to theangular length of the gap 41. At this moment the numeral 9 of thecounter wheel 1 is exposed through the win dow 23. When continuedrotation of the pinion 4| carries the pinion into the gap 41, the gear39 is free to rotate relative to the gear 31 under the influence of thetorque applied thereto by the spring 51. Consequently, the springrapidly forces the pins 53 and 55 towards each other. It

will be understood that the spring has sufficient torque to operate anyload connected to the gear 39.

As the spring 51 rotates the gear 39 to bring the pin 55 into the planecontaining the pin 53 and the shaft II, the counter wheel I is advancedrapidly for a distance corresponding to the angular spacing ofsuccessive numerals thereon. The gap 41 is so positioned that this rapidmovement of the counter wheel is eiiective to produce motion of thecounter wheel 1 between the numerals 9 and 0. Consequently, the counterwheels I, 3 and are always operated with a jump action.

It wil be noted that the wheel 1 does not move exactly in unison withthe shaft 35. Since this is a unit wheel, this slight variationordinarily is entirely acceptable. However, if desired, the numerals maybe omitted from the counter wheel 'I. It will be understood that thegearing bea tween the shaft and the gears 31 and 39 is selected toproduce a desired motion of the counter wheels.

Although the invention has been described with reference to certainspecific embodiments thereof, numerous modifications falling within thespirit and scope of the invention are possible.
